This is the H1+ case modified to fit common 18650 batteries and with added compatibility with the newer Heltec V4 module. Similar to my previous model.

Made with the request of and help from: @JLO_2137313

Also added separately printable letters model to print in a different color and glue in place for aesthetics, courtesy of: @JLO_2137313

Again:
WARNING:  LITHIUM BATTERIES ARE DANGEROUS.  BE CAREFUL! I AM NOT RESPONSIBLE FOR ANY KIND OF DAMAGE!!!

You can salvage electrodes from other battery holders and heat set them in place or you can just use folded up aluminum foil. A spring is heavily recommended.
